Subject: OSEM testing for SOSs 

29 Good OSEMs, of which 1 is questionable (089) with PD voltage of 1.5V, 5 need some work (pigtailing, replace/remove/add screws). We have 4 pigtails. Schematics.

20 OK OSEMs (Slightly off-centered LED spot), of which 3 need some work (pigtailing, replace/remove/add screws).

13 Bad OSEMS (Way off-centered LED spot)

2 Defunct OSEMs

-------

Ed: KA
Good: 23 complete OSEMs +  5 good ones, which need soldering work (there are 4 pigtails and take one from a defunct OSEM).
OK:  Use good 7 OSEMs for the sides. And keep some functional OSEMs as spares.
